SHEET-METAL CAN.

Specification of Letters Patent.

Patented Feb. 6, 1906.

Application Eled May 3i., 1905. Serial No. 262,976.

To atl whom, it may concern;

Be it known that I, HENRY MACARTHY, a citizen of the United States, residing in the borough of Brooklyn, city of New York, in

5 The county of Kings and State of New York,

invented anew and useful Improvement in Sheet-Metal Cans, of which the following is a speciiication.

My invention relates to improvements in sheet-metal cans, and more particularly to ,improvements in cans of large diameter, intending for containing and shipping heavy articles, such as ink, and having a deep tightfitting Harigeslip-cover.4

Heretofore'in the cans to which my invention relates when the cover has been once removed the mouth of the can becomes distort# ed because of the heavy contents of the can and difficulty is experienced in replacing the cover as required, the operation being somewhat 'like that ofthe joining sections of stovepipe owing to the large diameter of the can and the iiexibility of its mouth.

The object of my invention is toovercome these difficulties or objections; and it consists in the means I employ to practically accomplish this ob `ect or result, vas herein shown and describe In the accompanying drawings, forming'a part of this s ecification, Figure 1 is a top or plan View ofpa sheet-metal can embodying my invention. Fig. 2 is a vertical section on line 2 2 of Fig. 1. Fig'. 3 is an enlarged detail vertical section. Fig. 4 is a detail horizontal section on line 4 4 ol Fig. 2. Fig. 5 is a detail horizontal section'on line 5 5 of Fig. 2, and Fig. 6 is`a detail perspective view showing the two parts of the side seam of the canbody disconnected.

In the drawings, A represen ts the cai 1body of a sheet-metal can of large dianieter ein-` bodying my invention, the same having alap side seam a,formed bythe overlapping |neeting ends a a2 of the can-body blank, which are duly soldered together. This lap side seam extends over the whole vertical length' of the can-body.

B is the bottom head olf the can, the saine being united to the lower end el the am body by any suitable seam l1. '.lhe seam b, as indicated in the drawings, is a double seam; but it may be ol", any other desiredv folgm, soldered or otiierwisc.

Dis the sheetemetal cover, the same havmg a deep flange (l, preferably from one-half an inch to three-quarters of an inch in width or depth.

The sheet-metal can-body A is provided at its upper end with a downwardly-projecting external fold c and an upwardly-projecting external fold a4, having an outwardly-turned edge or roll fr". The wide integral folds a3 a4 of the can-body makes the can-body of three thicknesses and furnishes it with two stiflening and strengthening rings, greatly adding to the stiffness and rigidity of the can at its mouth or upper end and preventing it from becoming distorted when the slip-cover D is removed or when it is being removed and applied. The main body is )further stifiened and strengthened at its upper end by the turned edge or roll a5 at the upper edge of the outer ring or fold a4 and also by the curved portions a a7, which unites the fold or ring a3 with 4the can-body at the upper edge thereof and the folds or rings a3 and af* together. A narrow annular space is left between the downwardly-projecting fold. or ring a.3 and the upwardly-projecting ring or fold c* to receive the flange d of the slip-cover D between the folds or rings a3 and a4 and to aflord a tight lrictional fit or engagement between the llange of the slip-cover D and the integral folds or rings al,J a4 ofthe can-body. When 'the cover is applied, the upper end or mouth of the can-body is thus composed oi four thicknesses or rings at its upper end, which gives it the required strength and stillness to resist all danger of distortion in hamlling and shipment of the. cans even when filled withigo the heaviest articles.

The cover l) is provided with a ring D', preferably located near its riln or margin, for removing the cover. The cover l) may also be provided with an annular depression al at its rim, which in connection with the marginal turned edge or roll di ol the outer ring af;

ol' the can-bod lornis an annular Lrrove or? h channel to receive parallin or other adhesive 'substance which., il' desired, may be ap-v plied to more tightly seal the can. The cover Dis also preferably furnished with an external bead or liorizontally-projecting beador shoub der d, which tends to strengthen and stillen the cover,

At the side seam of the can-bod y the moet* IOO body having a Wide integral downwardly-k projecting fold or ring, and a Wide integral upwardly-projecting fold or ring terminating in a roll at its upper edge, the meeting ends lof Isaid folds or rings Aabutting together and.

being united by solder, and' the meeting edges of the canfbody blank overlapping each other and soldered together at the side seam ofthe can-body, of a slip-cover having an integral wide'flange tightly fitting between and engaging said integral folds or rings of the can-body,'said outer integral fold or ring of the can-body having'a roll at its upper edge to facilitate the entrance of the flange of the cover between the same and said inner down- Wardiy-p'rojecting oldjwhereby the frictional engagement of the cover With the can-bedr)T is increased and the upperend or mouth of the can-body stifened and strengthened and prevented from becoming distorted when the cover is being removed or replaced, substantially as specified.

2. In a sheet-metal can, the combination with a can-body having a plurality of external Wide folds or integral rings at its upper end, said rings being united and abutting to- 4 can-bod-yyhaving a rol aimee body, said outer integral fold or ring of the lcan-body having a rol at its upper edge, substantially as specified. y V

3. In a sheet-metal can, the combination with a can-body having a plurality of external Wide olds'or integral rings at its upper en d, said rings being united and abutting together at their meeting ends, and the meet-` ing edg,r i of the can-body blank overlapping each other and so'ldered together at the side seamr of the can-body,y of a cover having' a Wide slip-cover iiange iitting between and engaging said integral folds or rings of the can# body, said outer integral fold or ring of the at its upper edge, said cover having an externally-proyectin vshoul-` der or bead and an annular recess orming With said roll of 'said outer fold or ring of the can-body, a channel to receive'a sealing-ma*- terial, substantially as specified; I
